OSCAR E. BRACONIER, OF ROCKFORD, ILLINOIS.

IRONING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 619,703, dated February 14, 1899.

Application filed September 28, 1898. Serial No. 692,073. (No model.)

To a/ZZ whom it may concern:

Beit known that I, OSCAR E. BRACONIER, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Ironing-lVIachines, of which the following is a specification.

The object of this invention is the production of an ironing-machine simple and cheap enough in its construction to be adaptable to household use, for which purpose it is primarily intended.

In the accompanying drawings, Figure l is a side elevation of the ironing-machine. Fig. 2 is a longitudinal central section of the same. Fig. 3 is an end elevation, partly in section, of the mechanism. Fig. 4 is a view of the drivinggears and sprocket-wheels for the ironing-rollers, and Fig. 5 isatransverse central section through the ironing-rollers and the apron for feeding the fabric between them.

Like letters of reference indicate corresponding parts throughout the several Views.

A is the supporting-frame. A is the base therefor.

A2are thelower journal-bearings in the supporting-frame.

A3 are the upper bearing-openings in the supporting-frame.

B is a shaft mounted in the lower journalbearings A2 and is capable of a slight rocking movement therein.

B are arms fixed with relation to the shaft B,(l1avin g the j ournal-bearin gs B2 at their free en s.

B3 is the lower ironing-roller, having trunnions B4 for the journal-bearings B2.

B5 is a gear-wheel fixed to one of the trunnions B4. This gear-wheel meshes with the spur-gear B6, which latter, rigidly secured to the sprocket-wheel B7, revolves loosely upon the shaft B.

B8 is an arm or lever fixed on the rock-shaft B, intended to oscillate the latter and-to permit a yielding movement of the roller B3, with relation to the other ironing-roller. By this arrangement of gearing for the lower roller Bi3 the movement of the roller to and from the upper ironing-roller C does not alter or affect the mesh of its driving-gears, they remaining in the same relative position regardless of this movement.

C is the upper ironing-roller.

'C' are the hollow bearing-studs at each end of the roller C. C2 is a sprocket-wheel fixed on one of said bearing-studs.

C3 is a stud providing a journal for one end of the roller C. C4 is a hollow shaft which acts as the journal for the opposite end of the roller C and also permits the introduction of gas to the roller C for heating the same.

D is the inner tube of the gas-burner for heating the roller C. It is fixed with relation to the hollow shaft C4 and is perforated along its lower side to permit the escape of the gas to the outer tube of the burner. D' is the said outer tube, perforated along its upper side, at which perforations the gas is discharged to the flame.

E is a gasolene-gas generator of usual form.

E is the pipe leading from a gasolene-storage receptacle to the generator E, and E2 is a supporting-arm for said generator and pipe.

It will thus be seen that while the upper ironing-roller C .is fixed in its position in the supporting-frame A the lower ironing-roller has a yielding movement to permit dilferent thicknesses of fabric to be passed between the peripheries of the two ironing-rollers.

F is an expansion spiral spring located under the outer and free end of the lever B8, the tendency of which spring by raising the said lever and thereby rocking the shaft B is to throw the lower roller B3 into contact with the periphery of the upper ironing-roller C. The tension of the spring F is regulated by the hand-screw F.

F2 is a cam-lever by means of which the lower roller B3 may be withdrawn and held from contact with the upper roller C. When the cam-lever F2 is raised or released, the lower roller B3 is thrown into contact with the upper ironing-roller C by the force of the spiral spring F.

Gr is a movable carrier-apron for feeding the fabric to be ironed between the ironingrollers. It has a contact with the lower ironing-roller B3 at both upper and lower points in the periphery of the roller. The lower ironing-roller B3 is j ournaled slightly forward from the upper roller C, .whereby the apron Gis held in contact with a considerable por tion of the periphery of the heated roller C and is driven by the rol-ler B3. The apron IOO travels over and is supported at either end by the idler-rollers G, one of which (the one at the rear of the machine) is capable of an adjustment by means of the screw and sliding bearing-block G2 for changes in the length of the apron.

H is the drivin g-shaft, operated by foot or other power. H is a sprocket-Wheel fixed thereon.

H2 is a counter-shaft having three sprocketwheels H3, H4, and H5 iixed thereon.

H6 is an endless chain belt running over the sprocket-wheels H and H3. H7 and H8 are also endless chain belts running from the sprocket-wheels H4 and H5, respectively, and over the sprocket-wheels B7 and C2, respectively, driving the lower and the upper ironin g-rollers.

By the gearing provided for the lower roller its speed is made considerably slower than that of the upper roller, it being in practice about one to three, respectively.

In operation the gasolene-generator is started in the usual manner and the gas produced ignited at the heating-burner, which extends nearly the full length of and within the upper ironing-roller C. Of course illuminating-gas may be used for heating this roller when such gas is convenient. Vhen the heating-dame is burning, the machinery may be started and goods to be ironed laid on the carrier-apron G. The proper degree of pressure to be applied to the goods while passing through the ironing-rolls is obtained by adjusting the tension of the spring F by means of the handscrew F. The proper tension of the carrierapron G is obtained by means of the screw adjustment G2 at each side of the apron.

It will be noticed that any movement of the lower ironing-roller B3 toward or from the upper ironing-roller C does not disturb the relation of the former with the carrierapron G; but, on the contrary, the said apron is constantly driven by the said roller and an even tension maintained regardless of the movement of the roller.

The greater speed imparted to the upper ironing-roller C by the form of gearing shown causes the said roller to polish the surface of the fabric being ironed, imparting a smooth finished appearance thereto.

I claim as my inventionl. In an ironing-machine, in combination, a su pporting-frame, an ironing-roller rotatably mounted thereon, a rock-shaft also mounted on the frame, arms on the rock-shaft, an ironing-roller journaled between the said arms, a lever for moving the rock-shaft, a carrier-apron extending around the last-men-` tioned roller, two supporting-rollers for the carrier-apron, means for heating one of said ironing-rollers and means for driving the heated ironing-roller at a greater speed of rotation than the other ironing-roller, substantially as and for the purpose specified.

2. In an ironing-machine, in combination, a supporting-frame, an ironing-roller rotatably mounted on the frame, a heating-burner for said ironing-roller, a rock-shaft also mounted on the frame, arms on the rock-shaft, an ironing-roller journaled between the said arms, a lever for moving the rock-shaft, a carrierapron extending around the last-mentioned roller, two supporting-rollers for the carrierapron, means for adjusting one of said lastmentioned rollers and means for driving the heated ironing-roller at a greater speed of rotation than the other ironing-roller, substantially as and for the purpose specified.

3. In an ironing-machine, in combination, a supporting-frame, an ironing-roller rotatably mounted on the frame and having a hollow shaft-bearing at one of its ends, a g-as-burner within the said ironing-roller, a rock-shaft also mounted on the frame, arms on the rockshaft, an ironing-roller journaled between the said arms, a lever fixed tothe rock-shaft, a spring for the lever, a cam hand-lever engaging the iirst-mentioned lever, a carrierapron extending around the last-mentioned roller, two supporting-rollers for the carrierapron, means for adjusting one of said rollers, a driving-shaft and means for imparting motion to the two said ironing-rollers whereby the heated roller is caused to rotate at a greater speed than the other ironing-roller, substantially as and for the purpose specied.
